TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 496,507, dated May 2, 1893.

Application filed March 10, 1892. Serial No. 424,430. (No model.)

To all whom it may concern:

Be it known that I, HERBERT T. BARDWELL, residing in Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Type-Writing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention relates to type-writers and has for its object to provide a simple, cheap and efficient instrument.

One feature of my invention consists in a novel construction, as will be described, whereby the type-oarrier may be provided with a plurality of different characters, such as, small letters, capitals and figures, and whereby a single key may represent and effect the printing of each of the different characters, that is, each key may effect the printing of asmall letter, a capital,a figure, or any other desired character, as will be described. The typecarrier referred to is preferably made as a.

wheel or disk mounted on a preferably horizontal shaft and having a rotary motion in opposite directions, which may and preferably will be accomplished by means of cams, actuated by the key levers.

My invention further consists in novel details of construction which will be hereinafter specifically described and pointed out in the claims.

Figure l is a top or plan view partially broken out of a type-writer embodying my invention. Fig. 1 is a top or plan view of the remaining portion of Y the type-writer shown in Fig. 1, and is to be read in connection with Fig. 1.

A represents a bed-plate or base of wood, metal, or other suitable material, upon which the operating parts of my improved machine are supported.

In accordance with my invention, my improved type-writer is provided with a movable type-carrier, preferably made as herein shown, it consisting of a substantially large wheel or disk a mounted upon a shaft a,

herein shown as horizontally supported in bearings a on a post or upright a securedtp the bed-plate A, substantially near its longitudinal center. The horizontal shaft to is mounted in its bearings a so as to slide therein, and the said shaft has keyed upon it a beveled pinion or gear a (see Fig. 1,) with which meshes a segmental gear or rack a secured to or forming part of an arm a herein shown as forming part of ahub a loosely mounted on a shaft a extended the length of the machine, and having bearings in uprights 0. secured to the base A near its opposite ends. The hub a is prevented from moving longitudinally on the shaft a as herein shown, preferably by two bosses or hubs a e keyed or otherwise firmly secured to the shaft a The hub a is connected to the shaft a to movetherewith, as herein shown, by

means of a stud orscrew a extended through an enlargement or hub a ona rod a which is extended through arms a 0. on the hubs a a, and is fastened to the said arms by set screws a which, as shown, extend into slots a in the upper surface of the bar a the screw or stud a, after passing through the enlargement or hub a, entering a cam-shaped groove or slot a in the hub a From this construction it will be seen that if the shaft a is moved, as will be described, the collars or hubs a a move with it, and through the intermediate connection of the rod to and stud a, the hub a is moved.

The shaft a has connected to it by depending arms 0. a rod a located, as represented in Fig. 5,below the shaft a and substantially in line therewith. The rod a is adapted to be engaged by cams a (0 secured to key-levers a pivotally mounted on the shaft (6 located at the rear of the machine, and having hearings in suitable uprights a (see Figs. 3 and 4). Each key-lever a has secured to it one of the cams a (1 the said cams being shown in Fig. 5 as rods, each of which is extended through a boss at on the key-lever and secured therein by set screw a The type-wheel or carrier to in my present machine is designed to have a rotary movement in opposite directions through an angle of about one hundred and eighty degrees, and the movement or rotation of the said typecarrier in one direction,may be effected by one-half of the key-levers,and the movement in the opposite direction may be effected by the remaining half of the key-levers. To effect this result, the cam a is bent or shaped in one direction, and the cam (L28 is bent or shaped in the opposite direction.

Referring to Fig. 5, it will be seen that the cam (1 has its end bent or shaped downward, so as to overlap the rod a and act on the front side of the rod viewing Fig. 5, and the cam 0. is bent or shaped upward, so as to act on the rear side of the rod a when a key-lever is depressed. The cam of, acting on the front side of the rod a moves the said rod in the direction of arrow 21, Fig. 5,and causes the shaft a to be rocked in the direction of arrow 22, and the cam hub a through the hubs a (L12, rod a and stud a, is moved in the direction of arrow 22, thereby moving the segmental rack a upward or in the direction of arrow 24, Fig. 4, and causing the type-wheel a. to be revolved in the direction of arrow 25, Fig. l. \Vhen a key-lever carrying a cam 01. is depressed, it moves the red at in a direction opposite to that indicated by arrow 21, and rocks the shaft a in a direction opposite to that indicated by arrow 22, and thereby moves the type-wheel in a direction opposite to that indicated by arrow 25. In this manner the typecarrier is revolved to bring the proper letter 011 its surface in correct position with relation to a paper-carryin g roll I), to place the desired character or letter in position to be printed. The type-carrier a may be returned to its normal or starting position, as herein shown, by a spring m, one end of which engages aV-shaped eye a secured to the shaft a, and the other end of which is secured to the base A.

Referring to Fig. 1, it will be noticed that the type'carrier or wheel a, is inclined, so that when the type-carrier is moved as will be described, to effect the printing of a character, only one point or surface of the type-wheel will be brought in contact with the paper-carrying roll I), as shown in Fig. 18, and consequently, only the desired letter or character will be printed. The type-carrier a may be brought in contact with the paper on the roll b, when a key-lever is depressed, by a mechanism, as will now be described. The shaft a near its end opposite to the type-carrier, has cooperating with it an upright arm 1), see Fig. at, which abuts against the shaft (1.. The arm Z) is fast on a shaft b having bearings in suitable uprights b at the opposite ends of the machine, and the said shaft has mounted upon it, rearwardly projecting arms b (see Fig. 5) connected together byarod 1:, located below and in line with the key-levers a Each key-lever is preferably provided on its under side with a cam or projection b, which is adapted to strike upon the rod b when a key-lever is depressed. on a key-lever, striking against the red I), moves the said rod downward, and'thereby rocks the shaft b so as to move the arm 1) forward or in the direction of arrow 30, Fig. 5, and thereby move the shaft a and its typecarrier forward in the direction of arrow 30, thus causing the type-carrier to impinge upon the paper on the paper-carrying roll I), and effect a printing of the letter or character represented by the key depressed. The papercarrying roll I) is mounted upon a paper-carriage or frame 11 represented in Fig. 4 as provided with depending arms Z) 1) having inwardly projectinglugs Z) extended substantially the length of the frame b and which enter into guideways or slots 12 (see Fig. 5) on the opposite sides of a bar or frame b ,secured to the uprights or posts a as herein represented, by countersunk screws I), shown in dotted lines, Fig. 4. The paper-carriage is provided on its rear side with rack-teeth I), (see Figs. 3, 4, and 8) with which engages a pawl Z1 pivoted to a carrier, shown as an elbow lever provided with the upright arm I) and with the substantially horizontal arm I)", the said elbow lever being pivoted to a suitable support or upright 12 on the bed-plate A (see Fig. 3). The arm I) is engaged on its under side by an arm 11 preferably adjustably secured on a rock-shaft Z1 by a set screw Z1 (see Fig. 1), the said rock-shaft having bearings in suitable uprights b near the opposite ends of the bed-plate A. The rock-shaft I) is connected near its opposite ends, byarms Z), to a rod 0 to which is fastened, substantially near the center of the machine, arms b having secured to them a spacing-key 11 the arms I), as represented in Fig. 1, being also connected to the rock-shaft (1 The key-levers (L29 are adapted, when depressed, to strike the rod 11 The cam b IIO and move it downward, thereby rocking the shaft b so as to move the arm 12 upward, and lift the arm I)", thus rocking the arm I) on its pivot and moving the pawl into on- 5 gagement with a new tooth of the rack b, so

that when the key-lever a is released, the carriage through the rack-bar Z9 and pawl 19 may be moved forward the desired distance, by the spring 12 encircling the pivot of the arm b". Each individual key-lever a is preferably provided with a hub 19 through which the shaft a is extended,and eachhub b is preferably provided with a coiled spring Z7 by which the lever a maybe raised or restored to its normal position, after it has been released by the operator, the said keylever being stopped in its upward movement, as herein shown, by a cam or projection b striking against the under side of the carriage-supporting frame 5 (see Fig. 5). The forward movement of the carriage, after each depression of a key-lever is limited by a stop, shown as an arm 0 (see Fig. 3), preferably adjustably secured on the shaft 0. by a set screw 0', the said arm being provided on its inner side with a hook or projection 0 (see dotted lines, Fig. 3), against which the cam projection 0 strikes, and by which the pawl b is disen gaged from the rack 1), thereby leaving the carriage free to be moved by hand in either direction. When the arm I) is moved by the depression of a key the cam projection 0 is moved away from its stopc and the pawl Z2 is thrown into engagement with the rack 11 by a spring 0 the latter spring being weaker than the spring 12 The arm I), which lifts the arm b to place the pawl 12 in engagement with a new tooth of the rack-bar, may be adjustably secured on its shaft Z2 by the set screw 5 as shown in Fig. 1, so that the said arm may have its outer end adjusted with relation to the arm I), to move the arm I)" a greateror less distance when a key-lever is depressed, to carry the pawl 11 over one or more teeth, according as it is desired to have the carriage feed a greater or less distance after each depression of a key-lever, but I prefer to permanently secure the arm 11 on its shaft 11 and adjust the position of the arm 0 on its shaft a when it is desired to vary the letter spaces. The type-carrier a has cooperating with it one or more ink-ribbons c 0 passed about drums c 10 loosely mounted on an arm or shaft secured to a vertical rod or car1ier.c ,as byaset screw 0 and the said carrier or rod 0 has secured to its lower end, substantially near the bed-plate A, a second arm or shaft 0 (see Fig. 20), upon which is loosely mounted like drums c 0 which cooperate with the drums c c and about which the ink-ribbons c c are passed. One of the inkribbons, as 0 may be a record ribbon, and the other ribbon, as 0 may be a copying ribbon, and in order that both the said ribbons may be readily used with the type-carrier, the shaft or carrier 0 is made movable across the machine, so that either ribbon may be brought into position to co-operate with the type on the type-carrier a. The ribboncarrier 0 may and preferably will be made movable, as will now be described.

Referring to Fig. 20, the ribbon-carrying shaft 0 is extended below the bed-plate A and is secured to asliding-rod 0 having bearings in brackets 0 depending from the under side of the bed-plate, the rod 0 being shown as extended through the side of the bed-plate and provided, as shown, with the handle 0, by means of which the rod 0 may be moved longitudinally in its bearings 0. Normally the record ribbon c is preferably in line with the type on the type-carrier a, and the ribboncarrier 0 is in the position shown in Fig. 1, but when it is desired to employ the copying ribbon 0 the ribbon-carrier 0 will be moved towardthe right in Fig. 20 until the copying ribbon c has been placed in line with the type on the type-carrienand' at such time I prefer to lock the shaft or rod 0 by a locking device, shown as a spring 0 engaging a notch e in the said rod. 7

In order that the ink-ribbon co-operating with the type, may be automatically fed a short distance, to present a new piece or surface of the ribbon to be acted upon, the drums c c" have secured to them a ratchetwheel 0 which is engaged by the push-pawl 0 (see Fig. 6), pivoted on a crank or arm 0 fast on the shaft b When a key-lever-is depressed, it strikes the rod 12 and rocks the shaft 11 forward, thereby moving the crank or arm 0 and its pawl 0 forward in the direction of arrow 300, the pawl slipping over the teeth on the ratchet-wheel 0 and when the key-lever is released, and the rock-shaft 71. restored to its normal position, the pawl 0 pushes the ratchet-wheel in the direction opposite to that indicated byarrow 300 and thereby feeds the ink-ribbon.

In order that each key-lever may be used to effect the printing of a plurality of characters, the different characters, such for instance, as the capitals, small letters and figures, are arranged about the type-carrier Ctlfl predetermined sequence or groups, each group consisting of ditferentcharacters, and the desired sequence to be printed is controlled by a positioning device, herein shown as the camhub a', as will be described. When three different characters are to be designated by one key-lever, the type-carrier a is sub-divided into divisions, each including three diflerent characters, and the same characters occupy the same relative place or position in each division, as for instance, a small letter and a figure or other character, will intervene be tween two succeeding capitals, and likewise,

a capital and a figure or other character will intervene between two adjacent or succeeding small letters, as represented in Fig. 3.

Referring to Fig. l9 .'the cam-slot a is provided with a substantially straight or hori zontal portion marked 2, and an upper and lower portion marked 3, 4, the upper and lower portions being at opposite ends of the slot on opposite sides of the substantially straight or horizontal portion 2. In the normal condition of the apparatus, the stud or pin a is in engagement with the straight or horizontal portion 2 of the cam-hub a", and at such time the type-carrier may be supposed to be in position to print a small letter. If now it is desired to print capitals, the stud or pin a is moved into engagement with the cam portion 3 of the slot (R and as a result, the cam-hub a is moved downward on its shaft in the direction indicated by arrow 31, Fig. 4, and the segmental rack a is moved in the direction indicated by arrow 24, thereby revolving, the type-carrier in the direction indicated by arrow 25, thus placing a capital letter in proper position to be printed upon the paper, carried by the paper-roll b. The stud or pin a is moved into the elevated portion 3 of the cam-slot, as herein represented, by depressing a finger key mounted on a shaft 0 supported on the bed-plate A, and having secured to it an upright arm 0 forked at its upper end to embrace the pin or stud a, the said shaft being also provided with a like finger key 0 extended in the opposite direction from the finger key 0 and designed to be operated to place the figures on the type-wheel in correct position, whenit is desired to print a figure. The finger keys 0 e are kept in their normal position represented in Fig. 2, preferably by springs c secured to the bed plate as by screws 0 and acting upon the under side of the said finger keys. \Vhen the capital finger key 0 has been depressed and the type-wheel a has been moved to bring a capital letter in correct position for printing, the manipulation of any of the letter key levers, while the pin a is in engagement with the portion 3 of the slot a will effect the printing of a capital of the particular key-lever depressed, and while the stud or pin a remains in engagement with the portion 3 of the cam-slot, nothing but capitals will be printed. By means of the finger key 0 the stud or pin a may be brought into engagement with the lower portion 4: of the cam-slot a and thereby revolve the typewheel a in the direction opposite to that indicated by arrow 25, so as to bring a figure on the type-Wheel in correct printing position, and while the pin or stud a remains in engagement with the portion 4: of the cam-slot, the key-levers may be depressed to effect the printing of the figures.

The capital and figure keys 0 0 may be locked in their depressed position by means of aloeking device, shown as pawls c c pivoted on an arm or upright 0 and adapted to engage teeth or notches e e on an upright or arm secured to the shaft 0 As herein represented, the arm 0' is turned to the left, viewing Fig. 9,When the capital finger key 0 is depressed, and the pawl e is engaged with the tooth 0 and when the finger key 0 is depressed, the arm 0' is moved toward the right, viewing Fig. 9,.and the tooth 0 brought into engagement with the pawl 0 The pawls 0 0 look the stud a in engagement with the particular portion of the cam-slot a with which it is engaged, until the pawls are positively disengaged from their 00- operating teeth 0 0 to permit the stud a to be brought back into engagement with the horizontal or middle portion 2 of the cam-slot (4 and thereby bring the type-wheel into its normal position. The pawls a are maintained in their normal position shown in Fig. 9, as herein represented, by means of a spring (1 (see Fig. 10) securedto the upright or arm 0 and having one end connected to the pivot e of the pawls. It will thus be seen that with the machine herein shown, each key-lever may be used to effect the printing of a plurality of characters. I have herein shown the cam-slot (1. so made as to obtain three different starting positions of the type-earrier, but I do not desire to limit myself in this respect, as it is evident the cam-slot may be provided with any desired number of irregular portions to etfect any desired number of different positions of the type-carrier.

In practice, my improved type-writer may and preferably will be provided with a frisket or slotted plate (1, having a slot d of the size of a type on the machine, and through which the type may pass and strike against the inkribbon. In Figs. 13, 14L and 15, I have shown several different forms of friskets, which can be used on the machine. In Fig. 14, the frisket (Z is shown as a metal ribbon or strip, and in Fig. 13, a slotted plate secu red to a metal strip or flat spring d, and in Fig. 15, a slotted arm on a rod (1" sliding in a bearing (1 and normally kept away from the paper-roll by a spring d encircling the said rod, the said hearing being provided with a slot (1 through which is extended a stud d on the rod d.

The machine may be provided with any usual or well known form of presser bar, by which the paper is kept in contact with the roll, one form being shown in Fig. 17 as consisting of a rod d" having spring arms (1 the said rod having bearingsin the carriage-frame, as shown in Fig. 16. The paper-roll b may be rotated step by step to elfect the spacing of the lines, by a mechanism such as shown in detail in Fig. 16.

Referring to Fig. 16, the paper-roll b has secured to it a ratchet-wheel 61 with which engages apush-pawl (1 011 an arm (Z loosely mounted on the shaft of the paper-roll, and provided with a lug or finger (Z carrying an adjustable screw or stop (1 abutting against a fixed stop, herein shown as the presser-rod d. The pawl (Z is kept in engagement with the ratchet-wheel (Z by a spring (1 When it is desired to feed the paper forward, to present a new surface to be printed upon, the arm (1 is moved by hand in the direction of arrow 40, Fig. 16, until the stop-screw (Z engages with its co-operating stop or presserbar (1 and When the paper-roll has been fed forward, the operator releases the lever d, and a spring 62 moves the arm cl back to its normal position, against a suitable back stop, herein shown as the usual scale 01 When the arm @1 is moved backward by the spring (Z it carries the pawl 62 with it, and engages the said pawl with a new tooth of the ratchet wheel. By adjusting the stop-screw (Z the amount of paper to be fed forward may be varied as desired, to obtain the desired or required distance between the lines on the paper. 1

The machine is provided with a bell 8 (see Flg. 3), secured to the base A, and adapted to be struck by a hammer 6', shown in said figure, as secured to a spring arm e extended up into the path of movement of a stop or lug e?, preferably adj ustably secured to the carriage 6 The stop e may be adjusted on the carriage to strike the hammer arm 6 at any desired point in the forward feed of the carriage. The carriage is also provided, as herein shown, with a lug or stop 6 adapted to strike a pin or projection e on the frame Z2 (see Fig. 4) to limit the backward movement of the carriage, when the latter is moved by hand back to its starting position. The pin or projection e is preferably made detachable from the frame 19 to permit it to be removed, when it is desired to remove the carriage from the machine.

In order to obtain a substantial uniformity between the different letters printed, irrespective of the size or width of theletters, each key-lever may be provided on its under side with a cam f represented in Fig. 7 as a depression or concavity in the lever which comes in contact with the bar 12 to effect a varying movement of the carriage. By means of the cams f on the key-levers, the rocking of the shaft 5 and thereby the movement of the arm 19 may be varied, to vary the forward move: ment of the carriage to obtain the desired letter space. For instance, a key-lever having a substantially wide letter, such as m, w, &c,, may have a cam f of such shape as to produce .a greater rocking of the rod b than a cam f on a key of a substantially narrow letter, as for instance, the letter i, l, &c.

I have herein shown one form of type-carrier positioning device for obtaining different starting positions of the type carrier, and while I may prefer the construction shown, I do not desire to limit myself in this respect, as other forms of devices may be used to accomplish the same purpose, such for instance, as shown in Fig. 21. 7

Referring to Fig. 21, the arm a is shown a secured to a hub 0. provided with an arm f having a stud or roller f whichis designed to fit into a hole or opening f in acam-shaped hub f having secured to it a handle or pointer f the cam-shaped hub having its periphery embraced by a forked arm f on a hub f fast to the shaft a The cam-hub f. is shaped,- so that when the handle is in its vertical position shown, the type-carrier is in position to effect shaft a.

a is rocked in the opposite direction by the cam-hub f and stud f, to place another set of characters in the starting position. When the type-carrier a is returned to its position at rest, by the spring a, any tendency of the shaft a and of the said type-carrier, to'vibrate before coming to rest, may be obviated by a brake or stop mechanism, shown in Fig. 11 as a spring f which bears against the I claim 1. In a typewriter, the combination with a movable type-carrier provided with a plurality of characters, a revoluble shaft on which the type-carrier is mounted, a gear or pinion on said shaft, a-rockshaft a a hub loosely mounted on said rock-shaft, a gear or rack connected to the said hub and in engagement with the gear or pinion on the typecarrier shaft, character keys to operate said rock-shaft, and a positioning device to operate the said hub without operating the rockshaft, substantially as described.
